Defuzzifier circuit is one of the most important parts of fuzzy logic controllers that determine the output accuracy. The Center Of Gravity method (COG) is one of the most accurate methods that so far been presented for defuzzification. In this paper, a simple algorithm is presented to generate triangular output membership functions in the Mamdani method using the multiplier/divider circuit and...

We formulate a supply-chain problem by:(1)casting it in the model of critical-path analysis as defined by predecessor/successor relations, and (2)allowing for mutual dependency among activity nodes applying Leontief’s input-output structure.

the sources of output growth of iranian agriculture over the years 1986-2001 has been examined, using a decomposition method within the input-output (io) framework. the three comparable io tables of 1986, 1991, and 2001 have been employed as the main data sources. output changes from a demand side perspective, and decomposition of the growth of output into components attributable to consumption...

The RAS method is an iterative procedure that bi-proportionally scales input–output table to be consistent with given row and column sums. It can used disaggregate annual national more detailed tables, such as regional, quarterly, domestic/imported tables. However, the regular two-dimensional does not ensure consistency of disaggregated tables original table. For this problem, we use multidimen...
